On my Therion 75c in wattage mode there is a blank bar under the wattage readout, when you want to save puff you click on that. On the Paranormal there is a replay screen that has the same blank bar that will flash save puff. I haven’t played much with the 75c yet or set up my profiles, probably why it looks different.
My select skips right over the bar, so it won't let me accept it.
